Bently Nevada 330103‑11‑16‑10‑12

Comprehensive Product Overview & Technical Guide (Offline Version)

1. Product Overview

The 330103‑11‑16‑10‑12 is a precision eddy current proximity probe designed for continuous, non‑contact measurement of shaft vibration, radial and axial displacement, and position in industrial rotating machinery.

It forms part of the 3300 XL proximity probe family, which includes a range of high‑sensitivity probes used for condition monitoring, machinery protection, and predictive maintenance.

The model designation (11‑16‑10‑12) identifies the following configuration:

• 11 mm probe tip diameter — for enhanced sensitivity and strong signal amplitude, often preferred in larger machine applications.
• 160 mm probe housing (case) length — suitable for medium‑depth mounting scenarios.
• 1.0 m system cable — offering flexible routing from probe to monitoring hardware.
• Connector option “12” — a specific locking/connector configuration for rugged industrial installations.

This probe is engineered to provide reliable and accurate data in demanding industrial environments that require real‑time insight into rotating machine health.

4. Technical Specifications

5. Product Description

The 330103‑11‑16‑10‑12 proximity probe employs eddy current sensing technology to provide non‑contact monitoring of shaft motion. An electromagnetic field is generated at the probe tip. As a conductive shaft moves within this field, variations are detected and converted into voltage signals proportional to displacement and vibration.

With an 11 mm tip, this probe offers strong signal levels suitable for larger machines or where greater measurement sensitivity is desirable. The 160 mm housing supports medium‑depth mounting, and the 1.0 m coaxial cable allows flexible routing to the monitoring electronics. The connector variant “12” refers to a specific industrial locking configuration for stable electrical and mechanical connection in vibration‑heavy environments.

The IP67 sealed construction ensures resistance to dust, oil contamination, and moisture, providing long‑term operational stability in industrial settings.

6. Applications

The 330103‑11‑16‑10‑12 is designed for use in preventive monitoring of rotating machinery such as:

• Steam turbines — monitoring radial and axial shaft motion.
• Gas turbines — tracking vibration and position to protect against failure.
• Large centrifugal compressors — detecting imbalance and misalignment.
• Industrial pumps — measuring vibration and shaft movement under load.
• Electric motors — evaluating rotor displacement and speed reference.
• Gear trains and heavy drives — assessing dynamic shaft behavior.

Typical measurement functions include:
• Radial and axial vibration measurement.

• Shaft displacement tracking.

• Shaft position monitoring relative to casing.

• Keyphasor or speed reference signal generation.

These capabilities support predictive maintenance, early fault detection, and machine protection.
